Definitions

  • the invention relates to an adapter for coupling a sorbent container to a sorbent vapor source, and to a sorption process using this adapter.
  • sorption technology a distinction is made between absorption and adsorption. The latter takes place, for example, in the case of solid adsorbents.
  • Known adsorption devices work as closed or open systems. In both systems, the working medium is exothermically sorbed by the adsorbent. The sorbed working fluid comes from a steam source that cools down due to evaporation. Since both system variants work in the absence of air during the sorption phase, the system pressure is given by the respective evaporation pressure of the working fluid.
  • Known apparatus use these sorption techniques to generate cold and / or heat.
  • a sorbent filling is contained in a sorption container, which is connected to the steam source.
  • the valve When the valve is opened, working fluid vapor flows into the sorbent filling, provided there is sufficient vacuum. If this is not the case, the air that has entered prevents a rapid sorption reaction.
  • Half-open systems therefore consist of a sorbent container which contains a sorbent, a working medium vapor source and a suction device which sucks air and non-sorbed gases from the system.
  • the object of the present invention is to provide an adapter, with the aid of which sorbent containers and working fluid vapor sources can be combined simply and in a variety of ways.
  • Suitable as sorbent containers are all containers which are suitable for holding a solid or liquid sorbent. They should be vacuum-tight and, if the sorbent is liquid, also vacuum-tight. Furthermore, they should have an inlet opening for the working fluid vapor, which allows a vacuum-tight coupling with the sealing seat of the adapter.
  • the sorbent container themselves can contain additional heaters to desorb the sorbent from the working medium after saturation. They can also be provided with additional heat exchanger surfaces in order to be able to dissipate the heat that occurs during the sorption reaction to an external medium, for example air.
  • sorbents known in refrigeration are suitable as sorbents, which form a suitable pair of reactants with a working medium.
  • water is primarily considered as the working fluid.
  • Tools such as alcohols or ammonia are less suitable.
  • Zeolite and silica gel are known as sorbents for water vapor.
  • Zeolites have the property of absorbing water vapor very quickly and in large concentrations. They are therefore a particularly advantageous sorbent for semi-open systems in which the working medium is water.
  • Types of zeolite are particularly advantageous which, although they absorb water molecules, absorb little or no air components. Since such types of zeolite do not sorb nitrogen molecules, for example, they are not desorbed during the later sorption of water vapor. The air components released during the sorption of water vapor would destroy the vacuum and prevent a quick reaction. In these cases, the connected suction device would have to be re-evacuated.
  • All vessels which have a sufficient opening for the working fluid vapor and which allow this outlet opening with the sealing surface of the adapter to be vacuum-tight coupling are suitable as a water vapor source.
  • cup-shaped double-walled vessels are also advantageous which contain a singable agent in the double-walled jacket, which binds aqueous substances, in particular water, and has good thermal contact with the inside of the vessel.
  • the use of vessels which are suitable for holding containers whose outer surfaces are contacted with an absorbent material is particularly advantageous. For example, metallic beverage cans, but also glass bottles, which come with a suitable, damp coat are surrounded.
  • the aqueous substance can be evaporated to such an extent that it solidifies. If the aqueous substance is pure water, the solidification vapor pressure is 6.1 mbar. For this purpose, the suction device must reach a pressure of less than 6.1 mbar.
  • the base body of the adapter in the form of a disk and to attach the sealing seat for the sorbent container on one side and the flat sealing surface for the vacuum-tight coupling of the water vapor source on the opposite side. Since sorbent containers and generally have a cylindrical geometry, space and material are saved in a disk-shaped adapter.
  • the sealing seat and sealing surface are arranged in two mutually opposite planes.
  • the sorbent container and the water vapor source have suitable standing surfaces, the water vapor source or the sorbent container can alternatively serve as a base. This means that both water vapor sources with top and bottom can be used Connect the outlet opening to a sorbent container using the same adapter.
  • the adapter can be prevented from falling off the sorbent container without the system being under negative pressure.
  • the adapter is also used to cover the sorbent container. It is always sensible to close the sorbent container if there is a risk that, if left open for a long time, atmospheric moisture would impair the sorbent's ability to sorb.
  • the separating means is a droplet separator which can close the flow channel to the sorbent container.
  • the system In order to separate the working fluid vapor source from the adapter, the system must be ventilated in the case of vacuum systems. To this end, it is particularly advantageous to provide the adapter with a ventilation valve, via which the working fluid vapor source is directly ventilated. In this way it is avoided that, for example in the case of ventilation via the suction device, the inflowing air entrains dust particles from the sorbent filling into the steam source.
  • the suction device contains, for example, a suction pipe, one end of which projects into the sorbent filling and the second end of which has a connection option for the suction device.
  • a suction pipe one end of which projects into the sorbent filling and the second end of which has a connection option for the suction device.
  • the adapter advantageously has a separate connection for the suction device, so that the sorbent containers only have to be separated from the adapter and not also from the suction device.
  • this connection can be an immersion tube, which is fixed at one end in the adapter and suitable connecting pieces for connecting the suction device and penetrates deeply into the sorbent container at its other end in order to draw off air and non-sorbed gases at a suitable point.
  • the penetration of the immersion tube into the sorbent container advantageously takes place within the sealing seat and thus through the inlet opening of the working medium vapor into the sorbent container.
  • a part of the suction line can also be firmly connected to the sorbent container and can also be exchanged with it.
  • an additional suction connection is provided, which connects the suction line with the adapter within the sealing seat.
  • the adapter (1) acc. Fig. 1 consists of a disc-shaped base body (2), with a sealing seat (3) for vacuum-tight coupling of a sorbent container (4) and a sealing surface (5) for vacuum-tight coupling of a water vapor source (6).
  • Sealing seat (3) and sealing surface (5) are each formed from a flat soft rubber ring that seals both the inlet opening (7) of the sorbent container (4) and the outlet opening (8) of the working fluid vapor source (6) with the adapter (1). connects.
  • the working fluid vapor source (6) is filled in the lower part with an aqueous liquid (9).
  • the sorbent container (4) contains a sorbent (10) in solid granular form.
  • the metallic shell (12) of the sorbent container (4) is pierced by a suction pipe (13), the inner end of which is provided with holes (14) and the outer end of which is provided with a hose connection piece (15).
  • a (not shown) connected suction device which frees the system of air and non-sorbed gases via the holes (14).
  • the sieve (11) is held in place by means of an inner flange (16).
  • the adapter base body (2) has a flow channel (17) in the middle for the flow of the working fluid vapor from the steam source (6) into the sorbent container (4).
  • a separating means (18) is attached to the base body (2) by means of a threaded screw (19) in such a way that, together with the flow channel (17), the working fluid vapor is deflected several times. During this deflection, entrained water particles are separated by centrifugal forces and do not get into the sorbent filling (10).
  • FIG. 2 also shows an adapter (1) according to the invention, coupled to a cylindrical sorbent container (4) and a likewise cylindrical water vapor source (6).
  • the suction line (13) in FIG. 2 is not led through the container casing (12), but opens into the inlet opening (7).
  • a suction connection (20) which contains an O-ring seal (21).
  • the sorbent container (4) shown here also contains a sieve (11) which is fixed to the suction line (13) by means of a flange (16) and a bead (22).
  • the suction line (13) is welded to the bottom of the sorbent container (4) and provided with openings (23) for extracting air and non-sorbed gases. These are sucked off by a suction device (not shown) through the suction line (13) and a suction hole (24).
  • This suction device can, for example, be connected to the connection (25) by a hose line (not shown).
  • a bore (26) is used to ventilate the water vapor source (6) and is closed by the underside of the soft seal of the sealing seat (3). To ventilate the interior, the sealing seat (3) only needs to be slightly raised at this point.
  • the adapter (1) can protect the sorbent container (4) from the ingress of atmospheric moisture.
  • the working fluid vapor source (6) in this embodiment consists of a double-walled vessel which contains a drink (28) which is filled in for cooling. Inside the double jacket, there is an absorbent agent (29) on the inner wall surface in good heat-conducting contact. The absorbent (29) is soaked in water.
  • a (not shown) hose vacuum pump (not shown) is connected to the connection (25) of the adapter (1) and with this via the suction line (13) air and non-sorbed gases from the sorbent filling (10) sucked in. As a result, air is also sucked out of the vessel (6) until the pressure has dropped below the water vapor pressure.
